"You cannot wash the cover. It is likely to fall apart."
Well, that seems to be the consistent response that I received from the sales folks in 3 stores, and calling customer service twice. Well guess what. THEY'RE LYING !
I've had my King model 5000, dual chamber for 4+ years now and am VERY happy with it.
Last week one of my pooches urinated on it, and my wife went into a tizzy. I immediately inquired and was told by everyone at SC that it CANNOT be washed and must be replaced.
CS was so nice on the phone. "We're going to pick up the first 64% of the replacement cost." were the first words she uttered. I was tickled pink. But the next words were ".and you'll pay only $276". I almost fainted.
Well, my wife and I decided to implement "Plan A".
Went to the local laundromat where they have LARGE capacity washers. We put the top cover (soiled section) into the largest machine on delicate.
We washed it TWICE, and then put it in the dryer for almost an hour.
SUCCESS !
